Weeping and Laughing: Eicha 5:18

(18) "Because of Mount Zion, which lies desolate (Lamentations 5:18)": And it once was that Rabban Gamliel, Rabbi Elazar ben Azarya, Rabbi Yehoshua, and Rabbi Akiva were walking along the road in the Roman Empire, and they heard the sound of the multitudes of Rome from Puteoli at a distance of one hundred and twenty mil. The city was so large that they were able to hear its tumult from a great distance. The other Sages began weeping, but Rabbi Akiva was laughing. They said to him: For what reason are you laughing? Rabbi Akiva said to them: And you, for what reason are you weeping? They said to him: These gentiles, who bow to false gods and burn incense to idols, dwell securely and tranquilly in this colossal city, and for us, the House of the footstool of our God, the Temple, is burnt by fire, and shall we not weep? Rabbi Akiva said to them: That is why I am laughing. If for those who violate God's will, the wicked, it is so and they are rewarded for the few good deeds they performed, for those who perform God's will, all the more so will they be rewarded.... The Sages said to him: Akiva, you have comforted us; Akiva, you have comforted us.
